Not a 12-cylinder engine, a triple-turbo 12-rotor engine. A 15.7-liter rotary engine. This is insane, and so is Rob Dahm.

Rotary engines (also known as Wankel engines and Wankel rotary engines) are quite different from piston or "reciprocating" engines. One of the distinguishing features is that they don't need ...

I have already written about LiquidPiston and its XTS-210, but Avadi's idea is even more striking: it is a reciprocating engine that works as a rotary. Imagine an ICE with a single piston.

In a rotary engine the typical Otto cycle takes place in an oval-shaped chamber in which a triangular rotor rotates, effectively taking the place of the pistons in a traditional engine.
